  • Patent number: 12659386
    Abstract: The present disclosure relates to systems and methods for in-transit protocol translation. Specifically, various approaches are described for translating protocols for intermediate networks in a way by which there is no need of support for encapsulation/decapsulation at the end hosts and does not require any changes to end hosts or transit networks. Various embodiments include intercepting traffic between one or more source client devices and a transit network; detecting a first communication protocol used by the one or more source client devices in the traffic; translating the traffic from the first communication protocol to a second communication protocol; and forwarding the traffic to the transit network using the second communication protocol.

  • Publication number: 20250358702
    Abstract: This invention provides methods and systems for seamless mobile connectivity between public and private cellular networks. The system dynamically switches user devices between networks based on location, radio signal availability, or preconfigured policies that prioritize private networks when within range. For devices with physical SIM cards, an embedded applet enables switching between operator profiles, while ESIM profiles deploy applets for selecting among multiple identities within a profile. All cellular traffic, whether on public or private networks, is routed through a cloud-based system for centralized security and policy enforcement. Network selection may be influenced by defining the private network as the Home Public Land Mobile Network (HPLMN) or scanning available networks via applet capabilities. The system supports unified subscription, connectivity, and service management via a cloud-based portal, ensuring reliability and security across diverse network environments.

  • Publication number: 20250350647
    Abstract: Disclosed is a method for implementing a Zero Trust Architecture (ZTA) to secure network resources by eliminating lateral threat movement and minimizing attack surfaces. A zero trust policy engine, positioned inline between user devices and network resources, receives and evaluates access requests by verifying user and device identities along with context information. Based on dynamic risk scores derived from these evaluations, the engine enforces least-privileged, identity-based access policies, selectively granting access exclusively to authorized resources. Connections are terminated and re-established through secure proxy techniques, with continuous inspection of traffic for threats and data loss. Adaptive security measures, including isolation through pixel-streaming and context-aware access adjustments, further enhance protection.

  • Publication number: 20250317826
    Abstract: The present invention provides systems and methods for cellular network performance monitoring and optimization, enabling SIM-based devices to dynamically adapt to changing network conditions for improved connectivity. The invention introduces a process that includes determining baseline path performance through detailed probing of network metrics, continuously assessing current path performance via real-time monitoring, and instructing the SIM to switch from its current connected mobile network carrier to an alternate carrier when predefined performance thresholds are not met. Switching instructions are securely delivered Over-The-Air (OTA) to the SIM, ensuring seamless transitions to the most efficient and reliable network path. The system leverages both active and passive application layer observations to optimize latency, throughput, and reliability while supporting diverse applications, including IoT devices, industrial systems, and consumer devices.

  • Patent number: 12408078
    Abstract: The present disclosure relates to systems and methods for cloud-based 5G security network architectures intelligent steering, workload isolation, identity, and secure edge steering. Specifically, various approaches are described to integrate cloud-based security services into Multiaccess Edge Compute servers (MECs). That is, existing cloud-based security services are in line between a UE and the Internet. The present disclosure includes integrating the cloud-based security services and associated cloud-based system within service provider's MECs. In this manner, a cloud-based security service can be integrated with a service provider's 5G network or a 5G network privately operated by the customer. For example, nodes in a cloud-based system can be collocated within a service provider's network, to provide security functions to 5G users or connected by peering from the cloud-based security service into the 5G service provider's regional communications centers.

  • Patent number: 12381916
    Abstract: Systems and methods are provided for controlling network access in a zero trust environment. A method, according to one implementation, includes the step of monitoring and controlling access between a user device and a network application using a zero trust policy engine having a Zero Trust Architecture (ZTA) in which no user, user device, or network application is inherently trusted. The method further includes the step of granting trust by allowing the user device to access the network application when identity and context information associated with a user of the user device is verified and when policy checks of the zero trust policy engine are enforced.
